To all whom it may concern:

Be it known that I, EMIL JAGENBERG, a citizen of the German Empire,residing at Dusseldorf, Germany, have invented new and usefulImprovements in Machines for Mounting Sheets of Paper or other Material,ofwhich the following is a specification - This invention relates to animproved machine for mounting a sheet of paper or other material -upon asuitable backing in sucha manner that the latter projects heyond theformer to form a surrounding margin.

In the accompanying drawings: Figure 1 1s a side elevatlon of myimproved sheet mounting machine; Fig. 1 is a detail of lever 18 andconnecting parts; Fig. 2 is a view similar to Fig. 1, showing the partsin a different position; Fig. 2 is a view similar to Fig. 1, showing theparts in a different position; Fig. 3 a side view of part of themachine;Fig. A an end view of Fig. 3; Fig.

. 5 an enlarged section on line 5-5, Fig 4;

Fig. 6 av diagrammatic viewof the backing and paper releasing means andadjoining parts, and Fig. 7 a similar view, showing the parts in adifferent position.

The numeral 1 indicates a table adapted for the support of the backingA, which may consist of a sheet of card board, metal, wood veneering,etc. A similar table 2 is provided for the support of the facing orsheet of paper B, to be mounted upon backing A. Both tables 1 and 2.have means for advancing the backing and facing, respec-' tively, andare so constructed that the facing is automatically pasted upon thebacking, in such a manner, that the desired margin is left around thesame. For this purpose table 1 is provided with a transverse bar 4:which serves as an abutment for the backing when the attendant placesthe latter upon table 1. After the backing has thus been properlypositioned, bar 4 is withdrawn and the feeding means for the backing arestarted. The latter comprise a pair of superposed and preferablyintergeared feed rollers 6,

i of which the lower roller is mounted in a fixed bearing of the machineframe and receives rotary motion from power-shaft 59 by a beltor'otherwise. Upper roller (3 is journaled in bearings 61 slidablymounted in standards 62 of the machine frame and normally presseddownward by springs 63.

During the insertion of a new backing, u per roller 6 is raised, whileupon the wit drawal of bar 4-, said roller is automatically lowered tostart the feed movement of the backing; The means for obtaining thisresult are hereafter fully described. Table/2 is provided in like mannerwith a displace able bar or abutment 3-, and with a air of feed rollers5, of which the lower rol er engages a fixed bearing and receives rotarymotion in suitable manner, while the upper roller is journaled inbearings 64 guided in standards 65 and influenced by a spring 66.

The means for operatin the bars and feed rollers are as follows To frame60 is'pivoted at 67, a hand lever 68 provided with a nose 1? which isadapted to engage a lever 18 secured to a shaft 19. The latter carriesan arm 68 influenced by a spring 45 which tends to turn lever 18 upward.To shaft 19 is keyed an arm 20 which is by an adjustable link 21connected to a lever 11 pivoted at 69 and normally drawn upward by aspring 70. Lever 11 is provided with a pair of stepped shoulders 9adapted to be engaged by the free end of an arm 7 secured to a shaft 13.The latter carries a hand-lever 15 and an arm 71,- to' which bar 3 isconnected. While her 3 is in its raised position, upper roller 5 is alsoraised for which purpose shaft 19 is provided with a: pair of levers 22which are, by lifters 23, connected to the slidable bearin s (34 ofupper rollers 5.

As t us described, the operation is as follows: When the machine isready to receive a new charge, the parts assume the position shown inFigs. 1 and 6, in which position levers 1.8, 22 and 11 are raised bysprings 45 and 70, respectively, while arm 7 engages lower shoulder 9tocorrespondingly raise bar 3. Upper roller 5 is thus also lifted offthe lower roller by levers 22 and lifters 23. The attendant first slipsa. sheet of paper B, to be provided with a hacking, into the gap formedbetween the spaced rollers 5, until the paper abuts with its forwardedge against raised bar 3. (The backing A, is inserted at the same timeinto the machine, its movement being hereafter more fully referred to).Hand lever 68 is then swung into the position shown in Fig. 2, so thatnose 17 will depress lever 18 to correspondingly lower lever 11 by link21. Lower shoulder 9 will thus be Withdrawn from arm 7, to cause bar 3to descend by gravity until arm 7 engages upper shoulder 9, (Fig. 7). Inthis way barB-clears paper B, and as the descent of lever-18 has alsocaused a cor responding downward movement of levers 22 and lifters '23,the upper rotating roller 5 will, by springs 66, be forced against thepaperand the lower roller 5, so that a corresponding forward movement ofthe paper takes place.

The paper, after leaving table 2, is conveyed by a pair of guide rollers7 2, to means of paper B, from table 2 to rollers 24 is'considerablylonger than that of backing A, from table 1 to such rollers. As feedrollers.

' 5 '5, and 6, 6, rotate with the same speed, means must be providedwhich permit the start. of the forward movement of the backing onlyafter the paper has already been advanced forsome distance. In order toobtain this result, the following construction has been devised: To theouter end of a counter-shaft 51 driven from main shaft 59,

by a belt or otherwise, is keyed a sleeve '52, upon which is'looselymounted a cam wheel 29. The'latter is adapted to be coupledto sleeve 52by a friction clutch 50 slidably mounted upon sleeve 52 andparticipating in its rotation by a suitable groove and featherconnection. Clutch 50 is normally pressed into engagement with cam wheel29 by a spring 53 interposed between the clutchand a'hand wheel 54.Wheel 54 is screwed upon the threaded end of sleeve 52, so that byturning the hand wheel, the tension of spring 53 may be properlyadjusted.

Cam wheel 29 is provided with a peripheral projection 30 which isadapted to be engaged by a roller 74. The latter is carried by one endof a reciprocating rod 31 guided in a bearin of frame 60. The other endof rod 31 1s pivotally-connected to an arm 32. fast on a shaft 28 havingan arm 76 which is influenced by a spring 77. To shaft 28 is secured anarm 27 provided with an adjustable abutment 26 engaging the rear end ofa lever 12 influenced by a spring 78. Lever 12 is provided at itsforward end with a pair of stepped shoulders 10 adapted to be engaged byan arm 8 fast on a shaft 14. The latter being provided with a hand-lever16, carries bar 4, by means of arms 79 fast on said shaft. To shaft 28are further secured a pair of arms connected by lifters 38 to slidablebearings 61 of upper roller 6.

When the machine is in its position of rest, (Fig. 1), arm 8 engageslower shoulder 10 of lever 12, so that bar 4 is raised above table 1.Arms 39 are also raised by the action of spring 7 7 so that upper roller6 is lifted oil' the lower roller. The attendant is thus cnabled to slipa backing sheet A, between rollers 6, until it abuts against raised bar4.

As above described, the operation of the machine is started by turninghand-lever 68 to cause the forward movementof paper B. After the latterhas traveled for a certain distance, bulge 30 of cain'wheel 29, which isnow coupled to counter-shaft 51, arrives opposite roller 74 to shift rod31 to the right, (Fig. 1). In this way shaft 28 is turned to raise arm27, which will, by abutment 26,

tilt lever 12, so as to withdraw lower shoulder 10 from arm 8. Bar 4will thus descend by gravity, while, owing to the'siinultaneous downwardmovement of levers 39 and lifters 38, upper roller (Swill, by springs63, be pressed. against backing A, and lower roller 6. The backing willthus be advanced to ward rollers 24 hereinabove referred to. T hevariops parts are so positioned, and their movements are so timed, thatbacking A, arrives between pressure rollers 24 shortly before paper B,is fed to this point. In this way the desired margin on the backing isobtained when the paper is pasted thereto during their passage betweenrollers 24.

Additional means are provided for locking upper rollers 5 and 6 in theirlowered position, and for automatically raising them when the facing andbacking, respectively, have been grasped by pressure rollers 24. Forthis, purpose there is adjustably secured by screws 56, to cam wheel 29,a. disk 80 having a projection 40 which is adapted to engage a lever 42pivoted at 41 to machine frame 60. Lever 42 is provided with nose 44which engages a corresponding nose 43 of lever 18 when lever 68 is swungto the left, (Fig; 2). To lever 42 is pivoted a rod 55 guided within abearing 81 of frame 60 and provided with a slotted end-piece 82. Thelatter is engaged by the lower end of a lever 37 pivoted at 36 andprovided with a nose 35 adapted to engage a nose 34 of a lever 27 faston shaft 28. Itwill thus be seen that when lever 18 is lowered throughhand-lever 68, its nose 43 will snap underneath nose 44 of lever 42-When, subsequently, bulge 30 of cam wheel 29 pushes rod 31 to the right,arm 27 a will also be lowered, so that its nose 34 engages nose 35 oflever 37. In this way bars 3 and 4 are maintained in their loweredposition, while upper rollers 5 and 6 are simultaneously locked in theirlowered position.

The parts are'so set that when the backing spondingly raise upper roller6 off backing A.

Simultaneously with the ascent of upper rollers 5 and 6, cam disks 29and 80, are uncoupled from shaft 51 in the following manner: Lever 18 isprovided with a laterally extending arm 46 into which is tapped a screw83. The latter rests against an arm 49 of a fork 48- pivoted at 57. Fork48 is provided with a pair of screws 84 engaging'a peripheral groove 85of clutch 50. It will thus be seen that the ascending lever 18 will,

,5 through arm 46 and screw 83, cause fork 48 to be swung outward touncouple clutch 50 from cam wheel 29.

After the paper B, provided with a back;

ing A, has left rollers 24, hand-levers 15 and 16 are raised until arms7 and 8 engage lower shoulders 9 and 10 of levers 11 and 12, re-

- spectively. Bars 3 and 4 will thus be raised to be in proper positionfor the introduction of new sheets of facing and of backing. After thesesheets have been properly positioned, as described, lever 68 is turnedto the left, to firstly, Withdraw bars 3 and 4, secondly, depressupperrollers 5 and 6, and thirdly, couple clutch 50 to cam wheel 29, sothat tlhe operation described is repeated.
